Groundwater governance and management practices vary considerably across the United States. To better understand groundwater governance strategies and practices connected to water quality in the United States, a team from the University of Arizona Water Resources Research Center designed and launched a nationwide survey in 2016. The goal of the project was to identify on-the-ground practices of groundwater governance that may help to improve and enhance management of the nation’s water supplies, particularly within the realm of groundwater quality. A state water professional was recruited in each state to participate in the nationwide survey. The report was prepared as a project funded by the Ground Water Research and Education Foundation (GWREF) of the Ground Water Protection Council and benefitted from the involvement of GWREF representatives throughout the formulation of the survey. The surveys were responded to online, with no in-person interviews conducted. This report presents major findings from the survey.
